ADJUSTABLE CYLINDER-RING- SLEEVE AND RING COMPRESSOR.

Application filed December 27, 1924. Serial No. 758,397.

The present invention provides a tool for compressing the packing rings fitted in grooves of a piston or plunger whereby to facilitate the entrance of the piston or plunger in the cylinder or barrel of an engine pump, jack, or like part.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, v a r i o u s changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

Figure 1 is a detail view of the tool,

Figure 2 is a top plan view of the compressor,

Figure 3 is a sectional view thereof,

Figure 4 is a detail view,

Figure 5 is a detail transverse sectional view illustrating the ratchet mechanism.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The tool comprises a spring band 1 of a length and width to encompass the piston or plunger, the packing rings of which are adapted to be compressed to admit of ready insertion of the piston or plunger in the cylinder or barrel of an engine or pump. A reinforcement 2 is provided at one end of the spring band 1 and a transverse slot 3 is formed in the band adjacent the reinforcement for the passage of the opposite end portion of the spring band there through. Straps 4 are attached at one end to the end of the spring band projecting through the slot 3 and these straps are of a length to pass around the spring band and serve as contracting means therefor. A roll er 5 is attached to the free ends of the straps 4 and is mounted in brackets 6 attached to the projecting end of the spring band and rotation of the roller 5 serves to wind the straps 4 thereon and to contract the spring band whereby to compress the piston rings of the part to which the tool may be fitted. A ratchet lever 7 is fitted to a projecting end of the roller 5 and provides convenient means for rotating the roller to wind the straps 4 thereon when operating the tool to contract the spring band and compress the piston rings required to be forced into their respective grooves so as to come flush with the outer surface of the piston plunger or like part. A suitable detent 8 is provided to prevent backward rotation of the roller 5 when rotated to wind the straps 4 thereon.

What is claimed is 1. A piston ring compressing tool, comprising an overlapping compressible band having one end wider than the remainder of the band and provided with a transverse slot to receive the other end of the band, a roller j ournaled on the outermost end of the band, a strap secured to the said outer end of the band, said strap extending around the hand, through said slot and secured to the roller, and means to rotate the roller to wind the strap thereon and contract the band.

2. A piston ring compressor, an overlapping band adapted to enclose a piston and ring, a roller journaled on the outermost end of said band, straps secured to said outermost end and enclosing the band and having an end secured to said roller, the innermost end of said hand being wider than the remainder thereof and bent outwardly and formed with a slot to receive the overlapped end of the band and the straps, means to rotate said roller, and a detent on said roller located between the strap ends secured thereto and adapted to hold the roller in adjusted positions.

In testimony whereof I affix my signature.
